EMPROVEMENT IN SEWER-BASINS.

Specification forming part of Letters Patent No. 132,757, dated November 5, 1872.

To all whom t may concern:

Be it known that I, EDWARD L. DYER, of Portland, in the county of Cumberland and State of Maine, have invented a new and useful Combined Gulvert, Cess-Pool, and Stench- Trap; and I hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, in which- Figure l is a sectional side elevation of my invention, shown in the position which it is intended to occupy in relation to the roadway and sidewalk of a street.

The object of my invention is to so arrange the different parts composing a sewer-basin as to render its operation more simple and efficacious than by the different modes of arrangement now in use, and by that arrangement to provide in a very convenient way for the removal of the sediment which collects in the bottom of the basin.

At A, Fig. l, is seen the roadway of the street. B shows the drip-stone in the gutter, sloping` down to the point L, where an orifice is out in the curb-stone, which orilice is provided with a grate, (not shown in the drawing, but which may be of any ordinary coustruction.) The point L is the point at which the surface-water from the street enters the reservoir D. This reservoir D is of a size sufricient to contain a quantity of the water in a state of rest for the purpose of allowing the debris to settle to the bottom, and, when so deposited as a sediment, may be removed at pleasure from the openin g at B, the cover of which is made removable for that purpose. When the water passing in through the grate at the induction-point L rises to the dotted line g, or, in other words, up to the level of the orifice at f, which is also secured by a D into the smaller reservoir I. To afford security from freezing, this reservoir I is covered to some depth by the earth or other material of which the roadway of the street is composed, as shown at H. This smaller reservoir I has pendent from its top the partition J, extending downward toward the bottom of the reservoir. edge of the said partition J for the eduction of the water into the sewer. At J is seen the partition, such as is commonly used as a trap for the noxious exhalations which arise from the contents of the sewer beyond. At H His shown the earth or other material surrounding the reservoir I. C shows the sidewalk, in the curb or edge stone of which the induction-ori tice L is cut. c

For the construction of the different parts any proper material may be used, as stone, brick, or con crete. The sediment will, in most cases, be deposited at n,- but should any pass over into the reservoir I it may be removed through the grating f, which is hinged at m for that purpose, the reservoir being of a si; e

sufficient to allow access into it.

What I claim as my invention, and desire to secure by Letters Iatent, is-

The reservoirs D and I and partition J, as combined with the passages L, f, and K, and cover B, in the manner as and for the purposes set forth.
